Application filed November 28, 1835, Serial No. 184,160. (No model.) Patenied in England March 20, 1885,1\'o. 3,597; in France October 14, 1885, No. 159,034, and in Germany October 14, 1885. No 12,030.

To aZZ whom, it may concern:

Be it known that I, LIONEL HA RVEY PEARCE, a subject of the Queen of Great Britain and Ireland, residing at Ooalbourne Brook, Stourbridge, in the county of \Vorcester, England, have invented certain new and useful Means for vaporizing and Distilling Liquids, (for i which I have been granted Letters Patent in Great Britain, No. 3,597 of March 20, 1885; in France, No. 159,034 of October 14, 1885, and in Germany No. 12,039 of October 14, 1885,) of which the following is a specification.

The object ofthis invention is to provide an improved means whereby water or other liq- 1 nids may be heated, and, if necessary, vaporized and subsequently distilled, the same being especially applicable under circumstances where heat resulting from the combustion of fuel is not available. For the purpose of this invention I employ mechanical energy to generate f riction,and apply the heat resulting therefrom to the liquid under treatment. I also employ means for condensing the vapor of the water or other .25 liquid.

My invention will he hereinafter fully described,andits novel features carefully defined in the claims.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a vertical longitudinal section in the plane indicated by the lines 1 1 in Figs. 2 and 3. Fig. 2 is a vertical transverse section in the plane indicated by lines 2 2 in Figs. 1 and 2. Fig. 3 5 is a horizontal section in the plane indicated by lines 3 8 in Figs. land 2.

Like letters designate like parts in all the figures.

In Fig. 2portions of the interior domes are broken away.

In the present illustration of this invention the liquid to be heated is containedin avessel, a, which may be cup-shaped as to its upper part. Its lower part consists of a hollow 5 stem, against the side of which the periphery of a wheel or rubber, b, bears with a regulated pressure. The wheel b,which may be of wood, is mounted on a spindle, 0, carried in forked bearingsd d of the movable frame d. The spindle c is provided at either or both extremities with a crank-handle, such as c, whereby the wheel I) may be rotated. The vessel a is carried in a block, f, preferably of wood, secured in a portion of the fixed framing, ,suit' ably formed for its reception. The movable frame (I is formed with an extension, d",th rough which an adjustingscrew, d", passes,'the extremity ofthe latter entering a socket,f, formed in the fixed frame, and bearing on a washer or other packing of yielding character, with which thesocketis lined. A stiffspiral spring may be substituted for the packing, if preferred. On tighteningthe screw (1 the movable frame 11, carrying the spindlebearings d d, is caused to slide in the frame 9, and to press the periphery of the wheel 1) against the side of the heating-vessel a. h is a wooden plank, to which the whole apparatus is attached, andz' a shield for protecting the underneath portions from injury. The vessel a having been charged with liquid and the wheel I) rotated, the friction of the latter upon the surface of the vessel generates heat, which is communicated to the inclosed liquid.

The operation described may be continued to the extent of vaporizing the liqnid,and the vapor evolved may be subsequently condensed. The apparatus illustrated in the accompanying drawings includes means for this purpose, and is of the following description: The heat ing and evaporating vessel a is surmounted by two or more concentric domes, 7.: la, clad with flannel or other material adapted to retain water or other cooling agent, which is fed to the exteriors of the domes by means of the drip-nozzles q q. Instead of clothing the domes kk their outer surfaces maybe roughened or corrugated, with a view to retaining the cooling agent. The domes 7.: k areinclosed within a cylindrical chamber, 7.5, in the upper portion of which is formed a supply-tank, m, for the coolingwater. The tank m also supplies the heating-vessel a, in amanner which will be described hereinafter. The vapor escaping from the vessel a is condensed upon the inner surface of the dome k and drains into trough a, whence it passes by the conduit 0 to the delivery-pipe 2. During this process the dome 7.: becomes heated and causes a portion of the water applied to its exterior to be evaporated. This vapor is in turn condensed upon the inner surface of the dome k, and, draining into the trough n, finds its way by the conduit 0 to the delivery-pipe p. A similar process of vaporization ensues from the eX- terior of the dome is, this vapor being condensed on the under side of the tank at and the interior of the cylindrical chamber It", the product flowing from the trough a to the pipe 1), as before. The troughs n n are inclined in the direction of their outlet-conduits, communicating with the pipe 12.

For supplying water to the exteriors of the domes his, the tank m is filled through the orifice m. By applying the mouth to this orifice and blowing into the tank the water is caused to flow through the ducts q q to the domes kk. Other means may, however, be employed to produce an air-pressure slightly exceeding that of the atmosphere upon the surface of the liquid in the tank m. The shoulder of each of the domes k k is furnished with a ring operating to intercept or check the water when the flannel or other coveriugis dry, and then there would be a tendency for the water to flow over the surface of the covering without properly moistening it. This is only designed as a precautionary device for retardingthe flow of the water when the surface is dry, and to give the covering time to absorb a portion of the water.

The heating-vessel a may be supplied with liquid in various modes. In the apparatus represented in the accompanying drawings it is assumed that wateris the liquid under treatment. In such a case I prefer to supply the said vessel with the overflow fromthe coolingwater applied to the exterior of the dome it, this water having already had its temperature considerably raised.

The means of collecting the water that flows from the exterior of dome k and conveying it to a suitable receptacle may be of any kind having substantially the character shown.

I employ a trough,r,at the base of the dome to receive the water, and any suitable pipe, 1' to convey it to a receptacle. This receptacle is mounted on a vertical pivot, s, and is provided at its lower extremity with a nozzle, 8, suitably formed for making a tight joint upon the inlet to the heating-vessel. The lower extremity of thelatter bends laterally, as shown, and terminates in a mouth, against which the said nozzle is forced by means of the set-screw t, fitted in a portion of the frame 9. The arrangement is more particularly adapted for use with liquidssuch as salt watercoutaining a large amount of impurity,whieh, on being precipitated, requires periodical removal.

In order to facilitate the withdrawal of the vessel a and receptacle 3 for cleansing or other purposes,the chamber 76 is mounted upon an arm, a, pivoted at 10. Upon removal of the fastening a the chamber k (carrying upon the internal ring, 1), the domes k k) may be raised and turned back, the orifice m being meantime temporarily closed to prevent the escape of liquid from the tank m.

In order to keep the distilled liquid which flows from the inner surface of the domes separate from the impure water that flows from the outer surface of the same, I employ, as I have explained, separate conduits or conducting devices for these liquids, the same comprising annular troughs connected by pipes of any kind with the respective receiving-vessels. For example, the annular trough n receives the distilled liquid from the inner surface of dome 7c, which liquid is conveyed thence by any form of conduit to vessel 1). The impure water which flows from the exterior surface-0f the dome 7t:lS received in ananuular trough, r, and is conveyed by any form of conduit or pipe from said trough to the receptacles. The arrangement of the conveying-pipes that lead the liquids from the troughs to the receiving-vessels is not important, and is within the knowledge of any ordinarily skilled workman.

Apparatus of the kind described is specially applicable for service in small boats at sea, for the purpose of preparing from sea-watersmall quantities of distilled water for drinking purposes.

I make no claim to the heat-generating mechism or apparatus of itself, as such devices are known and have been before proposed for this purpose; but

IVhat I do claim is-- 1. The combination of the domes k and 7c, the troughs a and a, the troughs r and r, the distilling-vessel a, and the rubber for producing heat by friction in the liquid in the vessel a, substantially as set forth.

2. The combination of the inclosing-chamber 7c, the water-tank m, the domes k and k, the several channels for carrying off the distilled water, the vessel a,arranged within dome 7c, and the adjustable rotary rubber 1), arranged to rotate in contact with the vessel a, substantially as described.
